Recent advancement in molecular breeding for improving nutrient-use efficiency in maize.

Abstract

Abstract This chapter defines nutrient-use efficiency and the relevance of nitrogen (N) and phosphorus (P) as essential macronutrients and the molecular regulation of their metabolism in maize. The efforts towards molecular breeding of maize to improve NUE and PUE are also summarized and discussed. Plant phenotyping as one of the main and challenging components of molecular breeding and the potential of genome editing approaches to implement current findings on maize are addressed.
